I've reviewed the clinical literature on Ceylon cinnamon extensively. The research is legitimate and the results are meaningful:
UCLA study: 66,624 individual glucose readings tracked via continuous monitors. 24-hour glucose concentrations significantly lower with Ceylon cinnamon. Effect size of 0.96 — which in clinical terms is large.
Journal of Inflammation: Cinnamaldehyde directly inhibits the NLRP3 inflammasome — the primary driver of chronic metabolic inflammation in Type 2 diabetes.
UC Davis: Ceylon cinnamon improves insulin receptor sensitivity at the cellular level — not through chemical override, but through actual receptor restoration.
The reason most patients who've tried cinnamon supplements saw nothing is not because the research is wrong.
It's because most products use Cassia instead of Ceylon, deliver a fraction of the clinical dose, and use dry powder capsules with poor bioavailability.
Fat-soluble compounds like cinnamaldehyde require a fat carrier — specifically MCT oil — to actually reach the bloodstream.
Pria is the only formulation I've found that meets every requirement the research demands: authenticated Ceylon, 7,200mg clinical dose, MCT oil delivery, third-party verified.
